Does Spam Assassin do Bayesian Logic filtering and if so are you 
training it on the 20% that is getting through?

With Popfile or K9 (neither of which rely on external Blacklists) 
after a bit of training you should get well about 80% 

Most people seem to get 98-99+% accuracy in email identification as 
good/spam after a while. 

Note: that is not the same as 98-99% of spam correctly identified
(With 50% spam and no false positives, an 80% spam detection is a 90% 
overall accuracy) But with the proportion of spam you are getting, 
I'd expect it to be better than your current 80%.
